IMPROVEMENT IN SEWING-MACHINES.

Specification forining part of Letters Patent No. 22,97, dated February15, 1859.

Be it known that I, WATSON SNYDER, of Newark, in the county of Essex andState of New Jersey, have invented a new and useful Improvement inBinding-Guidesfor Sewing- Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the same,reference'being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a perspective view of a guideconstructed according to my invention. Fig. 2 is a longitudinal sectionof the same. Fig. if) is a back end view of the same.

Similar letters of reference indicate corre sponding parts in theseveral figures.

My invention consists in the combination, with two fixed guides, one forthe under edge of the binding and one for the edge of the fold thereof,of an elastic plate operating in combination with the foot or pressurepad, sub stantially as herein described, so as to adapt itself todifferent thickneses of binding and of the materials to bound for thepurposeof effecting the gradual turning over of the binding on the uppersurface of the material to be bound, and of .holding the same fiat as itapproaches the foot-piece or pressure-pad.

. To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation.

A is part of the plate or table of a sewinging-machine on which thecloth or material to be operated on is laid.

B is the foot or pressure pad, which may or may not also constitute thefeeder.

O is the stationary guide for the edge of the under portion of thebinding, having a straight edge, a, to guide the edge of the binding ina line parallel with the plane of the feed-motion and at a properdistance from the needle,and having a lip, b, which overhangs the edgea. This guide is secured to the plate Aon that side of the needle towardwhich the feed-move ment takes place by a screw, 0. The space betweenthe lip b and the plate-A should besufficient to admit the thickestbinding.

D is the stationary guide for the edge of the fold of the binding,serving, also, as a guide for to binding of different widths the saidguide D is made adj ustable'toward or from the needle in a direction atright angles to the plane of the feed-movement by providing a slot, 6,for

the screw f, which secures it to the plate A.

E is the elastic plate, of a width equal at least to half of that of thewidest binding for which it is to be used, attached at one end byascrew, g, to the top of the guide D, at that end thereof which is onthe side of the needle .toward which the feed-n1ovement takes place, andhaving its other end extended a short distance under the pressure pad orfoot 13, which is beveled to admit the said spring underneath it withoutinterfering with the pressure of the said pad or foot upon the material,and in such a manner that the end of the said plate E also presses uponthe material. The said plate E lies close to the face d of the guide D,and occupies a position over the guide 0. Its elasticity is such as torequire the pressure of the foot piece or pad 13 to hold it down.

The operation is'as follows: The cloth or material to be bound,represented in blue color in Figs. 1 and 2, passes over the top of theguide 0 and under the foot or pressure pad B. The binding, representedin the same figures in red color, passes singly under the cloth andunder thelip b, and with one edge in contact with the edge a of theguide 1), and the part not un der the cloth works in contact with theface (I of the guide D, with its edge in contact with the elasticplateE. By passing in contact with the oblique face of the plate E thepart of the binding not under the cloth is gradually turned over on thetop thereof as it approaches the foot or pressure pad, and beforearriving under the pad is pressed flat bythe'plate E, the fold guided bythe face (1 being always parallel with the edge of the binding guided bythe edge a.

The advantages possessed by this combination of guides over all othersknown to me consists particularly in its being adjustable to variouswidths of binding, and in its adapting itself without adjustment to allthicknesses of material, tobe bound, as well as of the binding itself,admitting the binding with equal facility of the thinnest fabric or thestoutest quilted ing machines; neither do I claim the attach-' ing ofthe Whole binding-guide to the foot or pressure pad, so that it may becaused to rise and fall therewith, as that has been already patented byO. G. Boynton, June 1, 1854; but

What I claim as myinvention, and desire to secure by Letters Patent,is-:

The combination of the fixed lipped guide 0 for the under edge of thebinding, the fixed but adjustable guide D for the edge of the fold ofthe binding and the elastic plate E, operated upon by the pressure pador foot, the whole applied and operating substantially as and for thepurpose herein set forth.
